V HIENDRYX CVOMPANYLOF NEW HAVEN, CQNNECTICUT BIRD CAGE Ap licationfiled April 2 This invention relates to bird cages, and theembodimentwhichIhave selected to lllustrate and describe is a cage made up-, of'

cellulose esters material, such as 'pyralin. 5 Cages made of thismaterial have many advantages, for example, the possibilityof'constructing them in a great variety'of colors and combinationsof'colors, the high luster Which may be given themfso as to "add totheir ornamental and attractive appearance,

' and the fact that they may be readily cleansedand kept in a clean,sanitary condition. 1 Moreover, the nature of this material is such thatthe cross members of the cage may be 16 very easily oined together bytheuse of a SOlVGIItWhiCh' causes thesmaterial to flow to-' gether andunite so 'as to form a substantially one-piece structure. The inventionis not limited, however, to the use of this material.

.20' One obj i of 1 linventign isto Provide bird cagestructureofsanitary character, attractive in appearance, and convenient to use.

Another object of my invention is to provide a new form of rail foracage of this type;

V 2 5 7 Still another object of this invention is to provide a novelform of rail and joint therefor. i 7

To these and other ends,'the invention consists in the novel featuresand combinations 7 of parts to be. hereinafter described and of railjoint used with the rail shown in Fig. 6. a c The bird cage selectedtoillustrate the features of this invention, generally com-. prises a bodyportion 10, a supporting means parts.

11,'and a bottom portion 12. The body por tion 10 consistsin integrallyunited horizontal rails 13, 14 and 15 and vertical Wire-like 'rods16.The rails 13, 14 and15 are arranged cone shape, being secured beneath acone: ea V shaped cap 17, with which is associated a ball l8 and 'a'cagesupporting ring 19.

. 'The rails 13, 14. and 15 of'Figs h 1'10 5 inclusivefare formed ofstrip stock, across section of vvhi'ch'isinthe formofsaright e5 angle.This stock maybe obtained in this. shape or'may be'formed from-fiatstock by turning an edge of a flatstrip at right angles tothe remaindenI V v The stock is furnishedin long lengths and is cut up into thedesiredlengths to form a rail; These shorterlengths are bent about intothe formof the cagev and are of sufficient length to encircle theperiphery thereof. One

portion 20 of these shorter lengths is disposed-"i5 in substantially ahorizontal plane, with a remaining portion 21 extendingabout the outerperiphery. thereof and at right angles therei to. l Vhen applied to acage, theportion 21 ispreferably disposed in a depending positionrelatively to the portion 20, which latter forms a flat top surface-forthe rail. 7 i I The ends 22 and 23-of thesho'rt'lengths of stock: may beeither abutted, as shown at Fig. .4, or overlapped, as shown in Fig. 5.WVhen abutted, a piece of-the samematerial, 24, substantially square incrosssectioinis disposed between theportions 20 and 21 and overlaps-theends 22 and 23-of the" short length. A solvent for the material-used'is99 applied to "the adjacent surfaces of these Before 7 the solventevaporates, the

form an integral structure. thereof. l/Vhen theends 22 and; 23areoverlapped, solvent is applied to the contiguous portions causingthem to integrally unite. 1

The rail so formed is then heated orpre'ssed or'- oth erwise. formedintothe desired shape together and unites. hen the solvent li-as evaporatedthe material hardens and tlie rails and rods are integrally. united intoa onepiece structure with the rail portlon 2(lun1ted.

to the rods at the perforations, and the rail portion 21 united tothe-rods at the portions in contact therewith. A rigid and sturdystructure is thus formed, which is inexpensive to manufacture and ofdecorative appearance. I

A-rail, channel shaped in crosssection, is shown in Figs. 6 and 7, theopen or channel side 31 preferably being directed toward'the cageinterior. The strip ends 32-are' abut-ted and integrally. unitedtogetherby the application of a solvent for. the materialused.

The channel-shaped rail 31 includes in its structure, ahorizontallydisposed portion 33, and aportion 34: disposed at substantially rightangles to the portion 33'and about the outer periphery thereof. Anotherportion 35 parallelat o the portion 33 and directed in-:

wardly trom an edge of the portion 34:, completes the channel formillustrated.

Apart 316, preferably a piece of the. same material, is inserted betweenthe portions 33', 34; and 35,-and extends across the abutted ends 82 tooverlap the end-portions ateach-s'i'de of the joint and reinforce therail at this point. The part 36 is integrally united to the ads jacentrail portions by the application ofra solvent, to the contiguousportions thereof.

' By securing the rods or wireform elements in pertorationsin one flangeof the rail by interfiowing the material. by the use of a soi vent orotherwise, and causing, similarly, the interflowing of the materialbetween the sides of the wireform elements and those portions of anotherflange of the rail which lie substantially parallel and in contacttherewith, the connection between the rail and therods is made verysecure, and the angular rail firmly supports the rods andgives'verysubstantial reinforcement tothe structurev in thezonewhere the rail. isapplied.

Vhile I have shown and described prewireform elements ofcellulose ester,and a substantially horizontal rail of the same material surroundingsaid elements and securing them rigidly together in spaced relation,said rail comprising a single strip U-shaped in cross section bent tothe form of the cage with the space between the legs of the U openinginwardly towards the cage center, the free endsof the strip being joinedby direct "adhesion, and a block of cellulose ester re- 'ceived-"whollybetweenthelegs of the U and tending horizontally and the otherextend.-
